Methyl methacrylate adhesiveMMA

An adhesive designed to carry significant service loads as part of an engineered joint, transferring stress between substrates over the whole bonded area rather than at discrete fasteners. Epoxies, polyurethanes and methacrylates are the main chemistries, used in applications from aircraft assemblies to wind turbine blade bonding.

An adhesive or resin supplied as two separate components, typically a resin and a hardener, that begin to cure only once mixed. Two-part systems cure through the full depth of the joint without needing air or moisture, but demand accurate proportioning, thorough mixing and use within the pot life.

An acrylic polymer supplied both as a transparent thermoplastic sheet (acrylic glass) and as a fast-curing reactive resin. In liquid-applied roof waterproofing and industrial flooring, PMMA resins cure rapidly by peroxide-initiated polymerisation, including in cool conditions, allowing quick return to service.

A structural adhesive modified with a dispersed rubbery or thermoplastic phase that blunts cracks and absorbs fracture energy, improving peel and impact performance without a large sacrifice in strength or temperature resistance. Toughened epoxies and acrylics are standard for bonded joints subject to vibration, impact or peel loading.
